I have a 2018 model in New Zealand, approaching third anniversary, an inspection is required to extend the warranty to 5 years for the car and 8 years for the battery. Last service the dealer said O rings on the battery are to be replaced at some horrendous cost. However they didn't have the parts and since the car was and still is well below 30,000km it was left as is. A former service franchise told me today that the O rings are a 30,000km service item and has warranty implications if not done etc.
I cannot find any reference to this in the service schedule or online anywhere. I am assuming the O rings are to seal the 3 covers on the bottom of the battery case where the cable connections are. If so I would only expect to replace them if they are opened to check tightness of the connections but it seems a pretty simple job in any case.
Anybody got any information on this?
